Description

Technical Field

[0001] This utility model relates to the field of feeding technology, specifically to an irregular shaft feeding machine. Background Technology

[0002] In modern industry, feeders are indispensable equipment. The production and assembly of various products all require the feeding process. Traditional feeders are mostly used for transporting workpieces with regular shapes. However, for some irregular shafts, there may be positional deviations or even tilting during transportation, which may prevent the shafts from being transported to the designated position for automatic feeding and easily cause machine failure. Therefore, currently, irregular shafts can only be fed manually. This feeding method is inefficient and cannot meet the processing needs of modern industry. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing an irregular shaft feeding machine to solve the problems mentioned in the background art.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] An irregular shaft feeding machine includes a frame, on which a conveying device for transporting irregular shafts is mounted. Several support frames are spaced apart on the conveying device, and the irregular shafts are placed between two support frames. A receiving frame for receiving the irregular shafts is installed on the frame at the discharge end corresponding to the conveying device. A pushing device is installed on one end of the frame corresponding to the receiving frame, and the pushing device is used to push the irregular shafts to a designated position. A lifting device is installed below the receiving frame, and several slots are provided on the receiving frame. The lifting device can pass through the slots to lift the irregular shafts to the designated position.

[0006] As a preferred embodiment of an irregular shaft feeding machine, the conveying device includes a mounting base mounted on a frame. Chains are movably arranged on both inner walls of the mounting base. Several chain plates are installed between two chains and are hinged to each other. A support frame is correspondingly installed on each of the chain plates. A drive motor is also installed on one side of the mounting base and is connected to the chain drive.

[0007] As a preferred embodiment of the irregular shaft feeding machine, both ends of the two chains are connected to sprockets, and the two sprockets at the same end of the two chains are connected by a connecting shaft, and the output shaft of the drive motor is connected to the connecting shaft through a coupling.

[0008] As a preferred embodiment of the irregular shaft feeding machine, a guide plate is installed on the side of the receiving frame near the conveying device. The guide plate extends to a position close to the conveying device, and the gap between the guide plate and the conveying device is smaller than the diameter of the irregular shaft.

[0009] As a preferred embodiment of an irregular shaft feeding machine, the feed plate is inclined, with the top of the upper surface of the feed plate flush with the chain plate and the bottom of the upper surface of the feed plate flush with the receiving frame.

[0010] As a preferred embodiment of an irregular shaft feeding machine, the top of the receiving frame has a V-shaped structure, and a baffle plate is installed at one end of the receiving frame, while the pushing device is located at the other end of the receiving frame.

[0011] As a preferred embodiment of an irregular shaft feeding machine, the pushing device includes a mounting frame installed on the frame, a rodless cylinder mounted on the mounting frame, a first guide rod disposed above the rodless cylinder, a guide block slidably connected to the first guide rod, a slider on the rodless cylinder connected to the guide block, and a push rod connected to the guide block through a connecting plate, the push rod corresponding to the position of the receiving frame.

[0012] As a preferred embodiment of the irregular shaft feeding machine, the top feeding device includes a drive cylinder mounted on the mounting frame. The output shaft of the drive cylinder is connected to a drive plate. The drive plate is located below and parallel to the receiving frame, and several insert plates are mounted on the drive plate.

[0015] The beneficial effects of this utility model are:

[0016] The feeding machine of this utility model optimizes the feeding structure. By setting support frames between the chain plates, irregular shafts can be placed between the support frames, effectively preventing them from shifting during transmission. At the same time, the discharge end of the conveying device guides the irregular shafts into the receiving frame through the guide plate, and then the side pushing device pushes the irregular shafts to move laterally, so that the irregular shafts reach the designated horizontal position. Finally, the top pushing device pushes the irregular shafts to move longitudinally, so that the irregular shafts reach the designated height, so that they can be gripped by the robot arm. This utility model realizes the automatic feeding function of irregular shafts and can transport irregular shafts to the designated position, meeting the processing needs of existing industries.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figure 1 As shown, this utility model provides an irregular shaft feeding machine, including a frame 1, on which a conveying device 2 is installed. The conveying device 2 is used to transport irregular shafts, one end of which is the feeding end, which can be loaded manually or by machine, and the other end is the discharging end. Several support frames 24 are arranged at intervals on the conveying device 2, and the irregular shafts can be placed between two support frames 24, thereby restricting the front and rear directions of the irregular shafts and effectively preventing them from shifting during the transmission process. At the same time, a receiving frame 3 is installed on the frame 1 corresponding to the discharging end of the conveying device 2. The irregular shafts on the conveying device 2 will enter the receiving frame 3 after passing through the discharging end.

[0031] Preferably, the support frame 24 in this embodiment adopts a triangular structure, and the two support frames 24 can form a V-shaped structure, which increases the contact area between the support frame 24 and the irregular shaft, and can provide support for the front and rear ends of the irregular shaft, thereby improving the stability of the irregular shaft during transmission.

[0032] like Figure 2 and Figure 3As shown, the conveying device 2 in this embodiment specifically includes a mounting base 21 installed on the frame 1. Chains 22 are movably arranged on both inner walls of the mounting base 21. Several chain plates 23 are installed between two chains 22. The chain plates 23 are hinged to each other to form a chain plate conveyor belt. The support frame 24 is installed on each chain plate 23 and moves synchronously with each chain plate 23. A drive motor 25 is also installed on one side of the mounting base 21. The drive motor 25 is connected to the chain 22 for transmission.

[0033] More specifically, the drive motor 25 and the chain 22 can be connected in the following way: both ends of the two chains 22 are connected to sprockets, and the two sprockets at the same end of the two chains 22 are connected by a connecting shaft, and both ends of the connecting shaft are movably connected to the inside of the mounting base 21. The output shaft of the drive motor 25 is connected to the connecting shaft through a coupling. When the drive motor 25 starts, the drive motor 25 will drive the connecting shaft to rotate, and the connecting shaft will drive the two sprockets and the chain 22 to rotate, thereby driving the chain plate 23 between the chains 22 to move.

[0034] Preferably, the top of the receiving rack 3 in this embodiment adopts a V-shaped structure. The V-shaped structure can increase the contact area with the irregular shaft, thereby more stably supporting the irregular shaft and preventing the irregular shaft from moving.

[0035] like Figure 4 As shown, in order to guide the irregular shaft on the conveying device 2 to the receiving rack 3, in this embodiment, a guide plate 6 is installed on the side of the receiving rack 3 near the conveying device 2. The guide plate 6 extends to a position close to the conveying device 2, and the gap between the guide plate 6 and the conveying device 2 is smaller than the diameter of the irregular shaft. When the irregular shaft reaches the discharge end of the conveying device 2, it will enter the receiving rack 3 under the guidance of the guide plate 6.

[0036] Preferably, in this embodiment, the feed plate 6 is inclined, with the top of the upper surface of the feed plate 6 flush with the chain plate 23 and the bottom of the upper surface of the feed plate 6 flush with the receiving frame 3, so that irregular shafts can enter the receiving frame 3 along the inclination of the feed plate 6.

[0037] Since irregular shafts may move left and right during transmission, affecting the subsequent gripping by the mechanical claw, this embodiment addresses this technical problem by installing a baffle plate 32 at one end of the receiving rack 3 and a pushing device 4 at the other end of the receiving rack 3. When the irregular shaft enters the receiving rack 3, the pushing device 4 pushes the irregular shaft until it abuts against the baffle plate 32, thereby fixing it in the designated position.

[0038] like Figure 5As shown, the feeding device 4 in this embodiment specifically includes a mounting frame 41 installed on the frame 1. A rodless cylinder 42 is installed on the mounting frame 41. A first guide rod 43 is provided above the rodless cylinder 42. A guide block 44 is slidably connected to the first guide rod 43. The slider on the rodless cylinder 42 is connected to the guide block 44. The guide block 44 is connected to a push rod 46 through a connecting plate 45. The push rod 46 corresponds to the position of the receiving frame 3. When the rodless cylinder 42 is started, the slider on the rodless cylinder 42 will drive the guide block 44 to move laterally along the first guide rod 43. At the same time, the guide block 44 drives the push rod 46 to move synchronously through the connecting plate 45. Since the push rod 46 corresponds to the position of the irregular shaft, the push rod 46 can push the irregular shaft to abut against the baffle plate 32.

[0039] Preferably, the feeding device 4 in this embodiment can also be equipped with a sensor. The sensor can be installed on the connecting plate 45 or the push rod 46 as needed. When the sensor detects an irregular shaft on the receiving rack 3, it sends a signal to the control system, thereby activating the rodless cylinder 42 through the control system.

[0040] Since the distance that the robotic arm can descend and grasp is limited, in order to facilitate the robotic arm's grasping, this embodiment can also install a top-feeding device 5 below the receiving frame 3. At the same time, the receiving frame 3 is provided with several slots 31. The top-feeding device 5 can pass through the slots 31 to drive the irregular shaft on the receiving frame 3 to rise to the designated position, thereby facilitating the robotic arm to grasp.

[0041] like Figure 6 As shown, the top material device 5 in this embodiment specifically includes a drive cylinder 51 mounted on the mounting frame 41. The output shaft of the drive cylinder 51 is connected to a drive plate 52. The drive plate 52 is located below the receiving frame 3 and is arranged parallel to it. Several insert plates 53 are mounted on the drive plate 52. The positions of the insert plates 53 and the slots 31 correspond one-to-one. When the drive cylinder 51 is started, the drive cylinder 51 will drive the drive plate 52 and the insert plates 53 to move upward. The insert plates 53 will pass through the slots 31 and lift the irregular shafts on the receiving frame 3.

[0042] Preferably, the starting timing of the drive cylinder 51 in this embodiment can be delayed according to the start and stop status of the rodless cylinder 42. When the sensor of the pushing device 4 senses the irregular shaft, the rodless cylinder 42 is started first. After a few seconds, when the rodless cylinder 42 pushes the irregular shaft to the baffle plate 32, the drive cylinder 51 is started to lift the irregular shaft, thereby realizing the linkage between the pushing device 4 and the lifting device 5.

[0043] To improve the stability of the drive cylinder 51 when it moves, this embodiment can also install a second guide rod 54 between the drive plate 52 and the mounting bracket 41. The second guide rod 54 can provide guidance for the movement of the drive plate 52.

[0044] Similarly, the top of the insert plate 53 in this embodiment preferably adopts a V-shaped structure, which can more stably support irregular shaft parts.

[0045] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
